  8. A patient takes a lab test and the result comes back positive. It is known that the test
    returns a correct positive result in only 96% of the cases and a correct negative result
    in only 95% of the cases. Furthermore, only 0.007 of the entire population has this
    disease. What is the probability that this patient has cancer or not?
